GEOPHYSICAL SURVEYING METHODS IN A SITE INVESTIGATION PROGRAMME

The recent revision to BS5930 on Site Investigation Practice has emphasised the increasing role of geophysical methods as part of a site investigation programme. Since the publication of the original version of BS5930 in 1981 significant improvements have been made in many areas of geophysical surveying including:- 1. the introduction of new methods such as ground probing radar and cross-hole seismic topography. 2. the use of the micro-computer as part of the geophysical instrumentation. 3. the application of the improvement in computer technology in the 80's to enhance the ability to the geophysicist to interpretation of the geophysical data. In this paper, the changes that have taken place in geophysical surveying methods since 1981 are examined in relation to these points. Case histories are used to illustrate the significant improvement in the instrumentation, the collection, processing and display of the geophysical data, the interpretation of the data and finally their integration in the site investigation programme. It is shown that the improvement made over the past decade has resulted in geophysical surveying methods becoming more acceptable to the civil engineers and, hence, more widely used site investigation programme. Finally, future prospects for geophysical surveying methods are assessed and areas where greater application is likely are suggested. (A) For the covering abstract see IRRD 883023.
